#1036 Abrogation of Autophagy by Chloroquine in Neuroendocrine Tumor Cells Treated with mTOR Inhibitors Induces Apoptosis, While Reduction of Cell Proliferation is Due to a Chloroquine, Autophagy Unrelated, Lysosomal Effect

Introduction: The therapy options for patients with advanced NETs are limited. The mTOR inhibitors (mTORi), Torin1 and NVP-BEZ235, are known to suppress cell proliferation in NETs. However, cancer cells may use mTORi-induced autophagy to prolong survival, evading the anti-cancer effect. Chloroquine (CQ) and hydroxychloroquine (HCQ) have been shown to inhibit autophagy.

#815 The Effect of Autophagy Inhibitors Alone or in Combination with mTOR Inhibitors in a Neuroendocrine Tumor Cell Model

Introduction: Most patients with neuroendocrine tumors (NETs) require systemic treatment, often with a limited therapeutic effect. RAD001 and Torin1 are mTOR inhibitors (mTORi) known to suppress cell proliferation in NETs. However, cancer cells may use mTORi-induced autophagy to escape the anti-proliferative effect and to prolong cell survival. Chloroquine (CQ) and hydroxychloroquine (HCQ) inhibit autophagy.

#220 The Global mTOR Inhibitor Torin1 is More Effective than the mTORC1 Inhibitor, Everolimus, Alone or in Combination with Histone Deacetylases Inhibitors, in Suppressing Neuroendocrine Tumors Cell Proliferation

Introduction: Torin1, a new mTOR inhibitor that globally inhibits both mTORC1 and mTORC2, seems to impair cell growth and proliferation to a greater degree than rapamycin; its effects in NET cells are unknown.
